Abstract
The veterinary laboratories of the Russian Federation annually conduct monitoring studies of food products in order to identify pathogenic microorganisms, including Listeria monocytogenes. The article presents the results of the use of imported and domestic nutrient media in the veterinary laboratories of our country. It is established that the use of selective enrichment and differential diagnostic solid media from different manufacturers did not affect on the quality of examinations in laboratory practice. It is shown that the media with a higher cost did not differ in the effectiveness of detection and differentiation of pathogens from domestic nutrient media. We also indicated the cost of the study to identify Listeria monocytogenes. The results of the annual reports of the state laboratories of the Russian Federation and the Central Scientific and Methodological Veterinary Laboratory (FSBI CSMVL) for 2019-2020 on the control for biological safety of raw materials and food products were analyzed. In 2019, 12 studies were conducted at the FSBI CSMVL, of which listeria was detected in 616% of samples, and in 2,12 from 2020 samples – 15% were with listeriosis contamination. In state laboratories in 113, from 1,08 samples were infected 2019% with listeria, and in 39, respectively, from 3195 samples were contaminated 1,79%.
